They use a cleanable element that uses a sticky oil to trap dirt until the next cleaning cycle.
K n air filter mass air flow sensor.
The test bench can flow air through the sensor at variable flow rates ranging from idle to full throttle.
The k n representative however gave a compelling argument.

K n addresses maf mass air flow concerns and explains what really happens when oil gets on a maf sensor.
But back to the debate.
K n air filter adapters are perfect for the person looking to build their own intake system.
K n s laboratory technicians tested an over oiled k n air filter at a rate of 1 000 cubic feet per minute cfm on our filtration test stand which utilizes an absolute filter.
The short answer is no and of course there s more to this story than meets the eye.

That being said we ll describe how.
Each adapter is configured to work in conjunction with k n high flow air filters to ensure smooth non turbulent air flow.
K n makes a great filter i use several on my own vehicles.
When one reads about mass air flow sensor contamination it is important to recognize that a modern engine can use one of five distinct categories of air measuring devices each of which works on very different physics principles.
Each component is designed with the latest cad software to ensure exact tolerances and a perfect fit.
They also flow marginally better than stock but not enough to make much of a difference un.
